Summarized version:
Great product, great service!
Detailed version:
I made a mistake in ordering replacement universal joints for my '08 Jeep Wrangler Rubicon. Unfortunately, I did not realize this mistake until I installed one of the (incorrect) joints and it was FAR too small. My loss right? No. Extreme Terrain customer service offered to replace the incorrect item with the correct one - despite the fact one had been installed (and will not be taken out of commission)!
But more about the item you are looking at for your own vehicle... Check the suggested/recommended fit. I can vouch that this X-Joint for Dana 44 IS the correct item for the '08 Jeep Wrangler Unlimited Rubicon 3.8L
The fit is near perfect; there is about 0.0025" protrusion from the yoke - personally, I would prefer that amount of protrusion over any amount of recess. The joint is also stout. I have damaged u-joints in the past while pressing them into place, and did not have any sense I was about to damage this one. There is a capped plug to install a zirc fitting on all four ends, so there is no screwing up the orientation (install the zirc fitting(s) at the end of the project to cover your butt).

These are very good quality I have a press which you will need I like the fact that you can grease them down the road it took me all afternoon because I cleaned and painted all parts and put tube seals in also.
